Best light type?

I know one guy who uses a 1000 wt MH for his highland chamber. Maybe the heat during the time it's on helps create the temp swing that they prefer...

I'm confused

Yes, it does. 6500 Kelvin is supposed to be approximately the light color of the tropical sun at noon over the Equator. Good for your neps.

I almost fell for those, too, when I bought the lights for my first terrarium in an aquarium shop. Fortunately, the owner was an orchid hobbyist and told me that 18000 Kelvin is _also_ approximately the light color of the tropical sun at noon over the Equator, BUT at 100 feet under water on a coral reef. Sure, your plants _will_ go batpoop with a bunch of these lights. Unfortunately, only your aquatic plants (hence the name "Aqua-Glo")

cheers

You can use the aquaglow type bulbs that are basically blue actinic.  But you need to suppliment with some red spectrum for nonaquatic plants.  An incandescent bulb or a warm white tossed over the plants would do.  Personally I don't think they are worth the cost over a standard daylight type bulb in the 5000-6500k range.
